Scientists have made a major breakthrough in understanding how prevent Age Related Macular Degeneration (AMD) by controlling an inflammatory factor in the body called inflammatory component IL-18.

The disease makes it difficult to see out of the center of the eye because it causes yellowish/white deposits in the middle of the retina, obscuring vision. The middle of the retina is called the macula.

There is no therapy to treat the disease once it happens. The deposits in the eye are characteristic of ‘dry macular degeneration’ that often progresses to “wet” macular degeneration.

Progression of dry to wet AMD causes blood vessels begin to proliferate underneath the retina, leading to blindness.

Symptoms of the eye disease, which should be evaluated immediately, include straight lines appearing wavy, objects look further away or closer than they are, and doorways may appear crooked.

Over 200,000 people in the United States are diagnosed with wet macular degeneration each year.

Risk factors for the disease include smoking, being over age 60, female and family history. Caucasians are more prone to AMD than are other ethnicities. Other risk factors include hypertension and obesity.

Dr Sarah Doyle and Dr Matthew Campbell from Trinity College Dublin have published their findings in the journal Nature Medicine that drusen – the yellow/white deposits that accumulate in the macula - can lead to the production of two inflammatory components termed IL-1beta and IL-18.

Component identified that prevents AMD progression

"Traditionally, inflammation in the retina or indeed the eye in general is not beneficial and is a pathological hallmark of many eye diseases, including AMD. However we have identified, that one inflammatory component termed IL-18 acts as a so-called anti-angiogenic factor, preventing the progression of wet AMD" says Dr. Campbell in a media release.

Can I get my family doctor to give me a prescription for a anti-VEGF DRUG? Is Soliris or avastin available to treat my wet macular degeneration in my eyes. I guess I have known about having macular for yrs. or more. I hope I can get something done about it, before I go blind. Anything you can tell me about this. I would appreciate it. I am 75 yrs old. I have diabetes, and chronic kidney disease. Thank you, Connie Summers
Hi Connie: I'm so sorry about your condition. Here is a link that nicely reviews approved treatments for wet macular degeneration. You would want to speak with your doctor for a referral to an opthamologist. Best to you. http://www.allaboutvision.com/conditions/amd-treatments.htm
My Mom has dry Macular degeneration. Her eye sight has really declined the last couple years. Is there anything available that could help her from losing her eye sight or better yet improving it? Thank you!
Hi Carla. I am so sorry. Is your mother seeing an ophthalmologist for guidance?
Yes she is. There doesn't se to be much help
Carla, there is a new treatment that transplants a telescopic type lens in the eye. Copy and paste this to read more about how it works: http://www.centrasight.com/how_it_works
